lllmll'lll nn .saires PATENT .onirica CARL F. WILSON, OF BAY CITY, MICHIGAN WALKING-MACHINE.

.To all whomz't may concern:

V,Be it known that I, CARL F. WILSON, a f Icitizen, ofthe United States of America, y residing at Bay City, in the county of Bay and vState -of Michigan, have invented cer- -tain new and useful Improvements in Walku Y `ing-llachines, of which 4the following is a This invention relates to movable supportingdevices for dredging and Vother like machinery.

fOneobject of the invention is to provide l a moving support for dredges and the -like which ldoes not require a track-upon which to move it.

An .otherobject resides in the provision of i l'means for giving the support a step by step @movement to follow the work upon which it Y.is engaged. Y

, sion of a plurality of cables and Apulleys A further object resides in the provision of aamaclnne or device of theznature stated, .embodying means for moving the machine backward throughvthe instrumentality of the mechanism used for forward movement.

A still further ob]ect resides in the proviicing any of the advantages of the invention.

Fig. 8 is a sectional elevation of the clutch fused, and

F ig.l 9 is an endelevation of the clutch.

VIn the drawings, a pair vof spaced main vskid members 1 are provided upon which'are mounted at each end thereof, the Vbrackets 2 for :supporting the main framemembers 3 and 4, to which are secured the various transverse and longitudinal beams 5, located between the said members. Upon these beams can be carried dredge mechanism of any preferred type. i

The front member 3 of the main frame has mounted at its eXtreme ends the stud shafts 6 upon which are swingingly mounted the bell crank levers '7 having mounted on their lower arms the rollers 8.

Auxiliary Vskids 9, having channel irons l0 on their upper surface, are located Yon eachside of the main skids 1 and said channel irons 10 form tracks, which the rollers g8 of the bell crank levers 7 are adapted to traverse.

A shaft 11 is mounted `on twoV of the beams 5 and receives two members a Vand Z2 which Vare loosethereoii and adapted to be independently driven in any well known j manner.

ber c has a sprocket wheel 13 and a brake drinn 12 connected therewith. The sprocket wheels 13 and 13 are of different diameters.

Mounted between the same two beams supporting the shaft 11, is a shaftl 14 upon Vwhich is loosely mounted a sleeve l5 to Vfrom the sprocket wheel 13.

Two drums 18 and 13n are loosely mounted arately rotated with the sleeve 1 5 by throwing either or both into engagement with a clutch member 19. The two drums are positioned on the sleeve 15 by means ofcollars 20 and are provided with corrugatedrecesses 21 which receive thecorru'gated periphery 22 ofthe clutch member 19, thereby securely locking Vthe clutch member 19 and the drums together. The drums 18 Vand 18a 1: arethrown into and out of engagement withV The .member Vo has a sprocket vwheel 13 connected therewith and the mem- Y tween Ythree of the beams 5.

When itis desired to move supporting vdevice Vtogether.with the dredging or other i50 mechanism carried thereby, forward, it is onlyA necessary yto apply power to rotate the members a and Z2. This rotates the wheels Y 13 randr13f andfthrough the mediurnof the A l chains17'and 17 the sprocket wheels 16 and 16 are rotated, therebyY rotating theshaft 14 and the sleeve lp'rand'rthrough the instru- Y mentality of the pinions27 and 2.8, alsoro- Afie-,atil'lgv theshaft 29..
